@Thomas: I have looked into the application. We use it at BCC. We found that using the "Enable Localization" creates a lot of overhead, because for each design element there are additional files ( in package Explorer ) with each new language.

I have used the resource bundles in my former company. With this solution, you have one .properties file for each language without any overhead.

And also the centralized storage for the key/value pairs for a language are much better to handle than editing various .properties files ...
